| Popis: | QCD@LHC 2019, Buffalo, NY, US, 15 Jul 2019 - 19 Jul 2019 In this talk I present a new endpoint factorization theorem that generalizes the classic soft threshold factorization for Drell-Yan-like processes. It fully captures both soft and collinear dynamics, including nondiagonal partonic channels that are neglected in the standard soft limit. This allows us to construct a fixed-order approximant for the cross section that covers all singular limits in the partonic momentum fractions. Our factorization also enables the resummation of all large-x logarithms appearing in the Drell-Yan rapidity spectrum toward large rapidities. |
